Security During Autumn Relocation and Address Changes | 2026 Edition: Practical Guide to Service Notifications and Personal Information Management
Overview
From September to November 2026, the autumn moving season concentrates individuals changing their address due to job transfers, university enrollment, marriage, or post-retirement relocation. According to the Ministry of Internal Affairs and Communications “Basic Resident Register Population Migration Report 2025,” approximately 2.8 million Japanese residents are estimated to change their address during this three-month period, with each move requiring an average of 25–35 address change procedures including (1) residence registration and My Number, (2) driver’s license and passport, (3) banking, securities, and insurance, (4) credit cards and membership services, and (5) e-commerce and subscriptions. Meanwhile, the address change process itself becomes a security vulnerability period, with multi-faceted risks emerging such as (1) important documents delivered to strangers at the old address, (2) missed critical notices due to delays in document delivery to the new address, (3) phishing attacks disguised as address change notification emails, (4) credential stuffing attacks during the ID and password re-confirmation process for various services, and (5) mail theft through abuse of mail forwarding registrations.
This article provides practical and comprehensive security measures for individuals planning address changes during the autumn 2026 moving season, covering preparation one month before moving, risk management on moving day, initial response at the new address, countermeasures against address change scam emails, and comprehensive protection using SecureSS. This content directly applies to all individuals planning a move or address change, including office workers, civil servants, self-employed individuals, students, and elderly persons.
Why Security Matters Today
Security measures during relocation and address changes directly reduce the risk of actual harm in the following five scenarios. These are organized from cases published by IPA, the National Police Agency, and the National Consumer Affairs Center in 2025–2026.
- Preventing third-party delivery or theft of important documents sent to the old address (bank statements, credit card bills, tax returns, etc.)
- Blocking phishing attacks disguised as address change notification emails that steal IDs and passwords
- Preventing mail theft and fraudulent account opening through abuse of mail forwarding registrations
- Preventing credential leakage during ID and password re-confirmation in address change procedures for various services
- Preventing unauthorized access from neighbors due to improper initial configuration of wireless LAN routers at the new address
SecureSS’s Shadowsocks-based VPN with secure DNS function encrypts all communications when logging into various services for the dozens of address change procedures before and after moving, and automatically blocks connections to fake phishing sites, protecting the entire address change process. This article presents comprehensive security assurance by combining SecureSS with operational routines before and after relocation.
How to Approach It
Step 1: Preparation and Organization One Month Before Moving
Preparation one month before moving is organized into five stages. Stage 1 is “Listing Address Change Targets,” writing out all of the following and creating a list of approximately 25–35 items: (1) administrative procedures (residence registration, My Number, National Health Insurance, National Pension, etc.), (2) identification documents such as driver’s license, passport, and residence card, (3) financial institutions (banks, securities, insurance, card loans, etc.), (4) credit cards, electronic money, and QR code payments, and (5) e-commerce, subscriptions, and various membership services. Missing items will result in continued delivery of documents to the old address, creating third-party delivery risks. Stage 2 is “Setting Priorities,” determining: (1) Top priority: administrative, financial, and identification, (2) High priority: credit cards and utilities, (3) Medium priority: major e-commerce and subscriptions, (4) Low priority: infrequently used services, and (5) Cancellation candidates: take this opportunity to clean up unnecessary services. Stage 3 is “Organizing Mail at Current Address,” implementing: (1) reviewing the past six months of received mail, (2) confirming services under contract, (3) discovering hidden contracts (forgotten subscriptions, etc.), (4) organizing cancellation candidates, and (5) deciding on storage and disposal of important documents. Stage 4 is “Safe Disposal of Unnecessary Documents,” implementing: (1) shredding documents containing personal information, (2) keeping bank and credit card statements for at least three years, (3) keeping tax-related documents for seven years, (4) sorting photos and memorabilia, and (5) identifying documents recommended for digitization. Stage 5 is “Complete Password Review,” implementing: (1) strengthening passwords for major services (taking advantage of opportunities when re-login is required for address changes), (2) eliminating password reuse, (3) introducing password management tools, (4) enabling two-factor authentication, and (5) organizing old email addresses. These five stages of advance preparation allow you to proceed efficiently and safely through the address change process during the move.
Step 2: Practical Response on and Around Moving Day
Practical responses on and around moving day are organized into five items. Item 1 is “Careful Submission of Mail Forwarding Registration,” implementing: (1) strict identity verification with Japan Post’s e-transfer service, (2) utilizing the one-year forwarding period, (3) confirming completion of forwarding registration procedures, (4) vigilance against forwarding registration abuse fraud (where someone else secretly submits a forwarding registration), and (5) monthly confirmation calls to the old address (when possible). According to National Police Agency 2025 statistics, approximately 450 mail theft cases involving abuse of forwarding registrations occur annually, requiring particular vigilance in the months immediately after moving. Item 2 is “Personally Transporting Important Documents,” strictly: (1) not entrusting seals, passbooks, and ID documents to movers, (2) personally managing cash and valuables, (3) considering transportation risks for PCs and smartphones, (4) backing up important data before moving, and (5) assessing device loss risk during transport. Item 3 is “Order of Address Change Procedures,” planned implementation in the following order: (1) Priority 1: residence registration change (within 14 days of move-in), (2) Priority 2: My Number and driver’s license, (3) Priority 3: banks and cards (prioritizing online procedures), (4) Priority 4: utilities and telecommunications companies, and (5) Priority 5: e-commerce, subscriptions, etc. Item 4 is “Vigilance Against Address Change Scam Emails,” implementing: (1) verifying the authenticity of “We have confirmed your address change” emails from various services, (2) cross-referencing with official email addresses, (3) careful confirmation of link URLs, (4) recommending direct access to official sites by typing in the browser, and (5) phone confirmation with each company’s customer support when suspicious. Item 5 is “Physical Security at the New Residence,” implementing: (1) lock replacement (essential for second-hand properties, recommended for new builds too), (2) confirming delivery box availability, (3) security measures for mailbox lock, (4) confirming the type of front door lock, and (5) evaluating the security of the surrounding neighborhood. These five items of practical responses on and around moving day allow you to safely navigate the vulnerability period of the address change process.
Step 3: Using SecureSS and Establishing Comprehensive Security at the New Address
Using SecureSS and establishing security at the new address is organized into five components. Component 1 is “Using SecureSS During Address Change Procedures,” realizing: (1) full encryption of all communications when logging into various services, (2) eavesdropping prevention during procedures via public Wi-Fi, (3) DNS-level blocking of phishing fake sites, (4) unified protection across multiple devices, and (5) comprehensive protection for all family members. SecureSS’s Shadowsocks-based VPN is practical as comprehensive communication protection for all 25–35 address change procedures during relocation. Component 2 is “Initial Configuration of Wireless LAN Router at the New Residence,” strictly: (1) mandatory change of management screen password from default, (2) configuring WPA3 or WPA2-PSK, (3) changing the SSID from default, (4) updating firmware to the latest version, and (5) separating guest networks. According to NICT’s 2025 observations, approximately 12% of home routers remain at factory default settings and are subject to unauthorized access from neighbors. Component 3 is “Confirmation Cycle After Address Change,” implementing: (1) two weeks after change: confirming cessation of documents sent to old address from major services, (2) one month after change: additional changes for missed services, (3) three months after change: final confirmation of important documents still being forwarded, (4) six months after change: re-confirmation with six months remaining on forwarding deadline, and (5) twelve months after change: final check before forwarding deadline expires. Component 4 is “Unified Security for the Entire Family,” planning: (1) supporting address changes for services used by children and elderly family members, (2) managing shared family email addresses, (3) warning elderly parents about address change fraud, (4) protecting up to five devices with SecureSS’s family plan at ¥1,500/month, and (5) minimum protection with the individual plan at ¥500/month. Component 5 is “Cost Efficiency and Continuity,” planning: (1) cleaning up unnecessary subscriptions on the occasion of moving, (2) redirecting savings to security investment, (3) continuous protection with SecureSS at ¥500–1,500/month, (4) trial use with the five-day free trial, and (5) long-term security operations. SecureSS at ¥500/month and the family plan at ¥1,500/month are practical and economical investments as the foundation of continuous protection during the relocation process and at the new address. The combination of these five components allows you to comprehensively establish security before and after relocation.
Summary
Q: How long will mail addressed to my old address keep arriving after I move?
A: A realistic summary of the situation for mail addressed to the old address covers five points. Point 1, “Japan Post Forwarding Registration”: For one year after submission, mail addressed to the old address is automatically forwarded to the new address, a free service. Point 2, “Items Excluded from Forwarding”: Some items such as large mail, cash-on-delivery, and express mail are not eligible for forwarding and require separate handling. Point 3, “Mail from Businesses”: Banks, credit card companies, insurance companies, etc. switch to direct delivery to the new address within one to two months after the address change procedure is completed. Point 4, “Easily Forgotten Services”: Notifications sent approximately once a year (tax-related, annual insurance notices, etc.) are hard to notice immediately after moving; a review one year after the change is recommended. Point 5, “After the Forwarding Deadline”: After one year, undeliverable mail is returned to the sender, at which point you can identify remaining services. Completely stopping mail addressed to the old address after moving requires a planned response period of approximately twelve months.
Q: What are the typical patterns of relocation and address change fraud?
A: The five typical fraud patterns in 2025–2026 are as follows. Pattern 1, “Forwarding Registration Abuse”: A third party secretly submits a forwarding registration for the victim, diverting important documents addressed to the victim to the perpetrator’s location; approximately 450 cases per year according to National Police Agency 2025 statistics. Pattern 2, “Moving Company Impersonation Fraud”: After contracting at a low estimate, additional charges are demanded on the day and belongings are held hostage; many complaints filed with consumer centers. Pattern 3, “Address Change Confirmation Email Phishing”: Disguised as “confirmation of your bank or card address change,” IDs and passwords are stolen; increases during the moving season. Pattern 4, “Delivery Notice Abuse Fraud”: Fake delivery notices direct access to fake URLs or fake phone numbers, combined with SMS fraud. Pattern 5, “Security Deposit Return Fraud at Former Residence”: Unreasonable claims or fake transfer instructions regarding the return of security deposit at the old residence, exploiting post-move confusion. It is recommended to maintain vigilance against these frauds at two to three times the normal level during the months before and after moving.
Q: How does SecureSS help during the relocation address change process?
A: SecureSS’s Shadowsocks-based VPN provides the following five protections during the relocation address change process. Protection 1, “Full Communication Encryption”: Uniformly encrypts all communications when logging in and changing addresses at 25–35 various services, preventing eavesdropping of IDs and passwords. Protection 2, “Secure DNS Function”: DNS-level blocking of phishing fake sites reached via address change scam emails, serving as a last line of defense when accidentally clicking. Protection 3, “Public Wi-Fi Security”: Preventing man-in-the-middle attacks during procedures via untrusted Wi-Fi at hotels or internet cafes during moving work. Protection 4, “Unified Multi-Device Protection”: Up to five devices with the family plan at ¥1,500/month, unified defense for smartphones, PCs, and tablets, protecting relocation-related procedures for the entire family. Protection 5, “Cost Efficiency”: Protection throughout the entire moving season at ¥500–1,500/month, achievable at less than 0.1% of total moving costs. Meanwhile, the actual address change procedures themselves and evaluation of mover reliability are outside the scope of service, requiring independent research before contracting. SecureSS alone provides sufficient protection for communication security during relocation.
Security measures during the autumn 2026 relocation and address change process require three layers for safe moving: advance preparation, practical response, and continuous protection at the new address. SecureSS’s Shadowsocks-based VPN provides protection for the address change process during the moving season and continuous protection at the new address at ¥500/month and the family plan at ¥1,500/month. You can experience your household’s security environment during the five-day free trial period.
