Postal address verification mails a physical postcard carrying a one-time code and a QR link to the address the visitor gives. Entering the code — or scanning the card — proves they receive mail at that address. It takes days rather than seconds, so it is used where an address of record matters (regulated commerce, correspondence, deliveries) rather than as a first-line age check.
How it works
The visitor confirms an address in the verification window; ComplyAge prints and mails a postcard through the postal provider; the card carries a short code and a QR code that opens a one-shot confirmation page. Entering the code completes the verification. A card that fails to send can be re-sent free of charge; a card that never arrives can be replaced after a waiting period.
When to use it
Establishing an address of record for regulated commerce, confirming a shipping address before high-value delivery, or adding a physical-world signal to an identity that was otherwise verified online.
Timing and coverage
Cards arrive on the provider's postal schedule — typically several business days. US addresses are supported today; coverage elsewhere depends on the postal provider and is shown in the window before a card is sent.
Billing
Billed per postcard on paid plans. Re-sends after a failed send are free; replacements after non-delivery are billed as a new card.
Frequently asked questions
- How long does it take?
- Several business days from send to arrival, depending on the postal service. The window shows the card's status as it moves.
- What if the card never arrives?
- After the waiting period you can request a replacement from the same window. A card that failed to print or send is re-sent free.
- Does this prove age?
- No. It proves you receive mail at an address. Pair it with an accepted age method where a jurisdiction requires one.
