Direct answer
No. USPS explicitly says its change-of-address order only changes your mailing address with the Post Office. You must separately update the agencies and programs that apply to you.
Why separate updates matter
Some government mail is not forwarded, and an agency may use its own address of record for notices, eligibility, identity checks, deadlines, or jurisdiction. The IRS says USPS data may update its record in some cases, but you should still notify the IRS directly.
Common records to review
- IRS tax records.
- Social Security and Medicare contact information.
- USCIS address reporting and pending cases.
- Your state or territory motor vehicle office, voter registration office, benefits agencies, and tax authority.
- VA, student aid, passport, court, licensing, and local records when relevant.
Recommended action
Start USPS forwarding, then use a written checklist and save confirmation for every agency. Do not assume that receiving forwarded mail means the agency changed its official record.
