Yes—USPS could have returned your envelope as if it did not recognize you at your friend’s address, but the image cannot prove that; allow several days, then start SSA’s replacement process.

I applied for my first SSN and saw the SSA envelope in USPS Informed Delivery, but it never arrived. I’m temporarily staying with a friend, so my name isn’t on the mailbox. Could USPS have returned it because of the name, and how do I get a replacement?

摘要

An Informed Delivery image is not proof of delivery—USPS says the letter may arrive several days later. If it does not, a replacement is free, and SSA says the completed replacement is mailed in 5–10 business days.

After allowing USPS several days, you have two SSA replacement routes: online if SSA offers it for your situation, or an office appointment if it does not.

Start the replacement onlinefastest start

Open https://www.ssa.gov/number-card/replace-card and select ‘Get started.’ SSA says online filing is available depending on your situation and calls this the fastest way to begin. Use your full name with the mailing address formatted as your friend.

Use an SSA office appointmentif offline

If the online flow does not offer submission, call 1-800-772-1213, Monday–Friday from 8 a.m. to 7 p.m. in most U.S. time zones, say you need a replacement card because the first one never arrived, and make the required local-office appointment. Bring the original evidence listed below.

Both routes end with a card sent by mail; the local SSA office cannot print a card for you.

Watch out for

A preview is not delivery proofUSPS says mail may arrive several days after its Informed Delivery notification. If the preview was recent, allow those several days before treating the envelope as lost.
The missing mailbox name is possible—not provenUSPS uses when delivery was attempted but the addressee was not known at the address, and undeliverable First-Class Mail is ordinarily returned. That makes a return possible here, but USPS does not say that an absent mailbox label automatically causes one.
Use an address that will stay reliableForm SS-5 says to give an address where you can receive the card 7–14 days later. At your friend’s home, format it with and your friend’s full name so USPS can connect you to the known resident.
Photocopies are not enoughIf SSA requires an office application, bring original documents or a made by the record custodian; ordinary or merely notarized photocopies are not accepted.

下一步

These steps separate a normal Informed Delivery delay from a missing card, create a deliverable address, and get SSA to mail a free replacement.

If the preview was recent

Allow several days after the preview

Do not treat the preview as same-day delivery confirmation. USPS expressly says mail may arrive several days after the notification; wait those several days while your friend checks the normal mail at that address.

条件要求

The date the SSA envelope first appeared in Informed Delivery

Before requesting another card

Prepare a c/o mailing address

Write the address in this order: YOUR FULL NAME / C/O FRIEND’S FULL NAME / STREET AND UNIT / CITY STATE ZIP. Use it only if you can reliably receive mail there for the next 7–14 days, the receiving window printed on Form SS-5.

条件要求

Your full legal name
Your friend’s full name
The exact street address, unit number, city, state, and ZIP Code

After USPS’s several-day window

Report the nonreceipt and start the SSA replacement

Start at https://www.ssa.gov/number-card/replace-card. If you prefer phone help or the online flow does not offer submission, call SSA at 1-800-772-1213, Monday–Friday, 8 a.m.–7 p.m. in most U.S. time zones, and say: ‘My first SSN card was shown in Informed Delivery but never arrived; I need a replacement sent to a c/o address.’ The replacement is free, and the office cannot print it.

条件要求

The reliable c/o mailing address
Approximate date of your original SSN application
Date of the Informed Delivery preview

If SSA requires evidence

Submit online or attend the SSA appointment

Complete the online request if SSA offers it. Otherwise, attend the required appointment and use Form SS-5, https://www.ssa.gov/forms/ss-5.pdf. SSA says the card arrives by mail 5–10 business days after it completes the request.

条件要求

One current, unexpired identity document: U.S. driver’s license, U.S. state non-driver ID, or U.S. passport
If you are not a U.S. citizen: your foreign passport and a current, unexpired DHS document such as Form I-551, I-94, or I-766
If applicable as an international student or exchange visitor: Form I-20, DS-2019, or the required school/employer/sponsor employment letter
Original documents or copies certified by the record custodian—not ordinary or merely notarized photocopies

Optional recovery step

File a USPS Missing Mail search in parallel

Submit at https://missingmail.usps.com once seven days have passed from mailing. This USPS search is separate from the SSA replacement, so it does not replace the SSA report or application.

条件要求

At least 7 days have passed since mailing
SSA’s and your mailing addresses
Envelope size/type and a description of the contents
Any available mailing date or identifying information
