# Steam Phone Number for SMS Verification

Source: https://tempsmsverify.com/temp-number/steam · Last updated: 2026-10-23

A Steam phone number is optional: Steam uses it for contact info and account recovery, and strongly recommends adding one when you use the Steam Guard Mobile Authenticator. TempSMSVerify gives you a number that receives the Steam verification code online and charges you only if the SMS arrives.

## Can I use a temporary Steam phone number?

Yes, for a one-time Steam verification code. TempSMSVerify reserves a Steam phone number, shows Steam's SMS in your browser, and charges you only if it arrives. Steam rejects numbers it classifies as VoIP, so some numbers may be declined. If no code comes, your frozen balance is refunded automatically. Do not rely on it for long-term recovery.

## Steps

1. **Find Steam's phone prompt.** Open Account details > Add a phone number, or the authenticator setup in the Steam Mobile App.
2. **Add balance.** Top up at least $5 with Card via Stripe (Visa, Mastercard, Amex, Apple Pay, Google Pay); Crypto (USDC or SOL on Solana).
3. **Buy a Steam number.** Choose Steam and a country such as the United States, the United Kingdom, Canada, India, Germany. Live stock and price show before you confirm.
4. **Enter it in Steam.** Select the matching country and paste the number as digits only. If Steam flags it as VoIP, cancel for a refund.
5. **Type the code and secure the account.** Enter the SMS code, save your revocation code offline, and plan to switch to a number you own.

## Steam phone number: when does Steam ask for one?

You do not need a phone number to create a Steam account. Steam signs you up with an email, and the default Steam Guard method sends 5-character login codes to that email.

A Steam phone number comes in when you add contact info under Account details, when you set up the Steam Guard Mobile Authenticator in the Steam Mobile App (Valve strongly recommends a phone there, though it is not required), and in some account recovery steps. In each case, Steam texts a short verification code that you type back into Steam.

## Steam's VoIP rule and what it means for you

Steam Support states that it cannot accept new VoIP numbers because they do not meet its security requirements, and that some carriers using VoIP technology are blocked too. Steam tells you right away if it considers a number VoIP.

TempSMSVerify sources numbers from licensed providers, but only Steam decides which numbers it accepts. If Steam declines a number, no SMS is sent, so you are not charged. Cancel after about 2 minutes and try a number from another country.

## Steam Guard: be honest about what a temporary number can do

A Steam account often holds years of games, inventory items and Wallet funds. The phone number linked to the Mobile Authenticator is one of the ways you prove ownership if you lose your phone or the authenticator. A temporary number cannot do that job after it expires.

Our advice: use a temporary number to receive a one-off Steam verification code if you need to, then put a number you own on any account you care about.

- When you add the Mobile Authenticator, write down the revocation code Steam shows (it starts with R) and keep it offline.
- Keep the email on the account current and secured with its own 2FA.
- Never share Steam Guard codes or your revocation code with anyone, including people claiming to be Steam Support.

## Steam verification code: common errors and fixes

Steam is strict about number formats and repeated attempts. Enter the number without spaces or dashes and pick the right country.

| Message or problem | What it usually means | What to do |
| --- | --- | --- |
| Number considered VoIP | Steam's filter declined the number | Cancel after about 2 minutes (no charge) and try another country |
| Phone number format not accepted | Wrong country selected or extra characters | Select the matching country and paste digits only |
| Code not received | Steam has not sent it yet, or delivery failed | Wait a few minutes before resending. No SMS means a refund |
| Too many attempts | Steam paused requests from your account or network | Stop and try again later |
| Invalid code | An older code or a typo | Use only the newest code in your dashboard |

## Pay only if the Steam code arrives

When you buy a Steam number, the price is frozen in your balance, not charged. TempSMSVerify charges it only when an SMS reaches the number. If the code never comes before the number expires after up to 20 minutes, the full amount returns automatically.

While the number is active, you can request another Steam code on it at no extra cost. There is no subscription, and your balance never expires.

## Responsible use on Steam

Use TempSMSVerify only for your own Steam account and follow the Steam Subscriber Agreement. Alt accounts for review bombing, market or trade scams, phishing, VAC or ban evasion and account reselling are not allowed by Valve or by us. Read our Acceptable Use Policy at /acceptable-use.

## FAQ

### Do I need a phone number to create a Steam account?

No. Steam creates accounts with an email address, and the default Steam Guard method sends login codes to that email. A phone number is optional. Steam asks for one when you add contact info or go through some account recovery steps, and strongly recommends one with the Steam Guard Mobile Authenticator.

### Why won't Steam accept my phone number?

Steam does not accept numbers it classifies as VoIP, and it also blocks some carriers that use VoIP technology. It can also reject a number entered with the wrong country or extra characters. With TempSMSVerify, a declined number never receives an SMS, so you are not charged. Cancel and try another country.

### What does the Steam verification code look like?

Steam Guard email codes are 5 characters long and mix letters and numbers. When you add a phone number, Steam texts a short verification code to it. Copy only the latest code from your TempSMSVerify dashboard, because Steam rejects older codes from earlier requests.

### Should I link a temporary number to Steam Guard?

Only with care. The phone on your Mobile Authenticator helps prove ownership if you lose the authenticator. A temporary number expires after up to 20 minutes, so it cannot help later. Save your revocation code offline, and move valuable accounts with large libraries or inventories to a number you own.

### Why is my Steam SMS code not arriving?

Delivery depends on Steam and on the carrier behind the number. Wait a few minutes before resending, because repeated requests can pause new codes. If nothing arrives, cancel after about 2 minutes, and TempSMSVerify returns your frozen balance automatically and in full.

### What is a Steam Guard revocation code?

It is a recovery code Steam shows when you add the Mobile Authenticator, starting with the letter R. You use it to remove the authenticator if you lose your phone. Write it down and store it offline. Never type it on a site other than Steam or share it with anyone.

### Is it allowed to use a temporary number on Steam?

Verifying your own account is a normal use. Creating alt accounts to manipulate reviews, scam trades, phish, evade VAC or game bans, or resell accounts breaks Steam's rules and our Acceptable Use Policy at /acceptable-use. Valve can lock accounts used that way.
