Getting a phone number and a mailing address

Almost every application you make in your first month asks for a U.S. phone number and a U.S. address. Banks, the DMV, employers and government portals all use them to verify who you are. Getting both quickly removes the bottleneck from everything else.

Phone

Prepaid needs no SSN, no credit check, no contract

Same day

An eSIM can be active before you land

Address

Must receive paper post reliably — much still arrives that way

Cheaper

Lifeline discounts phone or internet for low incomes

A phone number

You do not need a Social Security number or a credit history to get one. What you need is to pick the right kind of plan.

Prepaid ("pay as you go") plans require no credit check, no SSN and no contract. You pay for a month at a time. This is the fastest route for a new arrival and can be arranged the day you land.

Postpaid plans are billed monthly in arrears, are usually cheaper per gigabyte, and normally require a credit check. Without a credit history a carrier will either refuse you or ask for a deposit of a few hundred dollars, refundable after a year of on-time payments.

Smaller carriers reselling the same networks are often half the price of the big three for identical coverage. Check which network a reseller uses and how well that network covers the specific area you live in — coverage varies far more across the U.S. than in most countries.

An eSIM can be activated before you fly, so you land with a working U.S. number. Most current phones support it.

If money is tight, Lifeline gives up to $9.25 a month off phone or internet service — up to $34.25 on Tribal lands — for households on low incomes or receiving benefits such as SNAP or Medicaid.

A mailing address

You need somewhere that can reliably receive post, because a great deal of official business still arrives on paper: your Social Security card, your driver's licence, immigration notices, tax documents, bank cards.

If you do not yet have a permanent home, the options are:

1. A friend or relative's address — simplest, but ask first: mail addressed to someone not on the lease is sometimes returned, and you must actually collect it.
2. A mailbox service with a real street address (not a PO box number). These accept parcels and courier deliveries and can forward mail.
3. A PO box at the post office — cheap, but many agencies and banks will not accept one as a residential address.

Some forms distinguish between a physical address where you live and a mailing address where post reaches you. Where both are asked for, fill in both honestly rather than repeating one; giving an address you do not live at as your residence causes problems with the DMV and with insurers.

Set up mail forwarding when you move

The U.S. Postal Service will forward first-class mail for a year after you file a change of address. It is worth doing every time you move, but treat it as a safety net rather than a substitute for updating each account directly — and note that it is one of the services with convincing paid look-alike websites. The real one costs about a dollar, charged only to verify your identity.

Start the address file straight away

Keep everything that arrives with your name and address on it: the lease, the first utility bill, bank statements. Two proofs of address are what the DMV, the school and the benefits office will each ask for, and building the file from day one is easier than assembling it under time pressure — see the documents to protect from day one.
