How to get a temporary phone number

7 min readby the readynum team

There are four realistic ways to get a temporary phone number: a free public inbox, a prepaid SIM, a second-number app, or a paid one-time verification number. They cost different amounts and fail in different ways. Here is all four, plainly — including where our own product is the wrong answer.

The four routes, side by side

Route 1 — a free public inbox

Sites publish a few numbers and display every message that arrives on them. You open the page, copy the number, and watch. Nothing to install, nothing to pay, no account. Ours is here.

Why they fail: the number is shared, so the platform has very probably seen it before. Popular free numbers have been used on every major service already — the account slot is taken and your signup bounces. Some ranges end up on fraud-prevention blocklists that platforms subscribe to. And every code is readable by everyone, including whoever else is using the number right now.

When a free number is genuinely enough — and it often is:

  • A signup you will never need to recover: a forum, a one-time download, a wifi portal.
  • Reading what a service actually sends before you give it a number you care about.
  • A code you wouldn't mind a stranger seeing, on an account with nothing in it.
  • Checking whether a service accepts virtual ranges at all, before paying to find out.

If one of those describes you, stop reading. You don't need to buy anything, and we'd rather say so than sell you a number for a job a free one does — the longer version is in free vs private numbers.

Route 2 — a prepaid SIM or eSIM

The most durable answer and the least convenient. A prepaid SIM — physical or eSIM — gives you an ordinary mobile number with an ordinary carrier behind it. It makes calls, banks accept it, and it survives as long as you keep it topped up.

The costs are real. Many countries require identity registration before a prepaid SIM is activated — Germany, Spain and Poland among them — so “temporary” here does not mean “unregistered”. And the carrier reclaims an inactive number eventually, on a schedule in its own terms.

Take this route when you need to keep the number, call from it, or use it with a bank. Those are precisely the jobs the other three cannot do.

Route 3 — a second-number app

Google Voice, Skype Number, and the second-line apps. You install something, sign up, and get a number you can call and text from, usually monthly. The right tool for a durable second identity: a work line, a number for the ad you posted.

Two limits. Availability is narrower than the marketing suggests — Google's own support pages state that the personal tier of Google Voice is a United States product and ask for an existing phone number at signup, which is awkward if the reason you're here is that you'd rather not give one out. And platforms that screen virtual ranges screen these too: an app number is as visible as a VoIP number as any other.

Route 4 — a paid one-time number

The narrow tool: a number rented for one verification, with the message shown in your browser, priced per code rather than per month. No app, no SIM, no keeping it. Here is the whole flow, with the United States as the worked example.

  1. Pick the service and the country. Start from Telegram numbers or from the United States. That pairing decides whether the code arrives, so it's the first decision, not a detail.
  2. Read what the page says before you pay. Each route shows its price, whether a number is buyable right now, and what we know: a figure measured from our own orders with the sample size and window; a named supplier's figure marked as theirs; or the sentence "We don't have data for this route yet". On a new site most routes are the last one — the honest state, not a broken widget.
  3. Top up for one order. Minimum deposit never exceeds the price of one order. Your balance never expires. Prices are on the pricing page with no account needed to see them.
  4. Rent the number and keep the tab open. You get the number and a browser inbox listening for the incoming SMS.
  5. Enter the number, then copy the code back. When the SMS arrives it appears in your inbox. Your codes are yours. We auto-delete received messages after 24 hours — often you're the only one who ever sees them.

And the failure branch, because there is one: if no valid code arrives, take a different number free or let the order refund itself to your wallet. You don't pay for codes that don't turn up — the refund policy says exactly that. Routes fail for knowable reasons, laid out in why verification codes don't arrive.

What about a “fake” number?

A common search, and it deserves a direct answer. Numbers that belong to nobody do exist: North America's numbering administrator reserves 555-0100 through 555-0199 for fictional use, and Ofcom sets aside blocks such as 07700 900000 to 07700 900999 for drama. Real reservations — and they receive nothing, which makes them useless for verification, because verification is the act of receiving something.

The other version — typing in a plausible number that isn't yours — sends a stranger your code and your spam. It's somebody's actual phone. If you need a code, you need a number that reaches you and that you control while the code arrives.

Which route should you take?

  • One code, once, on an account you'll never need back → a free public number is enough, and free is the right price.
  • One code on an account you care about → a paid one-time number: the inbox is yours, and a failure is refunded rather than argued about.
  • A number people can ring you back on → a second-number app or a prepaid SIM. Not us: we receive SMS and nothing else.
  • An account you must keep, or anything touching a bank → your own number, on a SIM, in your pocket. No temporary option survives a re-verification a year later.

That last line is the one worth remembering. Temporary phone numbers, explained goes further into the boundary, what is a burner number covers it from the privacy side, and the trust page explains how we label every figure here.

Temporary phone number FAQ

What's the fastest way to get a temporary phone number?

A free public inbox — you open a page and the number is there. Whether it works for your signup is a separate question, and often the answer is no, because the platform has seen the number before.

Can I get a temporary number without giving an email address?

For a free public number, yes — there's no account at all. For a paid one we ask for an email so we can send the code and the receipt, and nothing else.

Do temporary numbers work for WhatsApp and Telegram?

Sometimes, and not uniformly. Both screen the numbers people sign up with, and outcomes vary by country, by range and over time. We publish what we've measured per route and say where we've measured nothing — the WhatsApp guide walks one through end to end.

How long does a temporary phone number last?

A one-time rental lasts the length of the verification — minutes. A free public number stays up as long as the site keeps it, but you never own it. If you need the number next month, you're in the wrong category.

Start where the decision gets made: pick a service or a country — price, availability and route state are on the page before anything is charged.
