You need a phone number. You don't need it forever. Maybe it's for a marketplace listing, a dating phase, a one-time verification, or a short-term project that'll be over in a few weeks. The point is that it goes away when you're done.

That narrows the field more than you'd think. Most second phone number apps are designed for permanence. Here are the ones that actually handle temporary well.

Why Temporary Matters

A temporary phone number is useful in the same way a hotel key card is useful — it works perfectly while you need it and stops working the moment you don't.

People who sell on Craigslist or Facebook Marketplace don't need a buyer's number hanging around after the transaction closes. Dating app users don't need a match's access to persist after things fizzle. And anyone who's ever signed up for a free trial using their real number knows what happens next: an endless stream of texts from a service they used once.

The appeal of temporary isn't that the number is low-quality. It's that the number is fully functional while it exists and completely gone when it's not. Real calls, real texts, real voicemail — then nothing.

What to Look For in a Temporary Number App

Not every app that offers a phone number handles the "temporary" part well. A few things to check before you commit:

Can you actually delete it? Some apps give you a number but won't let you erase it cleanly. Google Voice, for example, ties your number to your Google account semi-permanently. If you can't delete the number and all its history on your terms, it's not temporary — it's just a second number you'll eventually ignore.

Does it work for verification? If you need the number to sign up for a platform or receive a verification code, standard VoIP numbers often get rejected. Mobile-classified numbers have better compatibility.

Is it a real number or a shared receiver? Free "temporary number" sites often give you a public number that anyone can see incoming messages on. That's fine for reading a one-time code from a low-stakes signup. It's not fine for anything involving personal communication.

What does it cost — honestly? Some apps advertise "free" but require credits for every text and call. Others charge a flat monthly rate for unlimited use. Know what you're paying before the first message.

The Best Temporary Phone Number Apps

Burner

Burner was built for this. The app's core concept is numbers you use and then erase — the clue is in the name.

Two options fit the temporary use case. Prepaid burners give you a number for 30 days with 50 minutes and 100 texts. Use it for a transaction, a dating cycle, or a short project, and let it expire — or burn it early. Everything attached to that number disappears permanently.

Subscriptions work if your definition of "temporary" is more like a few months. Unlimited calls and texts, auto-renewing, and you can delete the number whenever you're done. Separate voicemail, do-not-disturb, auto-reply — all the features of a real phone number with the ability to walk away cleanly.

Burner numbers are mobile-classified, so they work with most platform verification — Cash App, PayPal, Facebook, Amazon, and more. That's a real differentiator from free VoIP alternatives that get blocked.

Best for: Marketplace selling, dating, short-term projects, anyone who wants a real temporary number with full functionality.

Pricing: Subscriptions start with a free 3-day trial. Prepaid burners available for one-off use.

Hushed

Hushed offers a similar privacy-focused approach with a pay-as-you-go option that works well for truly occasional use. If you need a number once every few months, paying per minute/text rather than a monthly subscription can make more sense.

Multiple numbers are available, including international options. The app is functional if not particularly polished. Call quality can be inconsistent, particularly on international lines.

Best for: Infrequent use, international numbers, pay-as-you-go flexibility.

Pricing: Plans from ~$3.99/month. Pay-as-you-go credits available.

Google Voice

Google Voice is free and functional, but calling it "temporary" is a stretch. You get one number tied to your Google account, and removing it isn't straightforward. There's no burn/delete feature, no permanent history erasure, and no real privacy separation from your Google identity.

It's also standard VoIP, so many platforms reject it for verification.

That said, if you just need a free second number for basic calling and texting and you don't care about deleting it later, Google Voice works. Think of it as a permanent second number you happen to use temporarily.

Best for: People who want free and don't need deletion, privacy, or verification.

Pricing: Free.

TextNow

TextNow gives you a free number with ads. Unlimited texting and calling, no subscription required. The trade-off is ads in the app, VoIP-based calling (verification issues), and number recycling — if you don't use the number regularly, TextNow may reassign it to someone else.

Number recycling is the big issue for temporary use. Ironically, the less you use it, the more likely you are to lose it before you're ready.

Best for: Free texting when you don't need verification or privacy.

Pricing: Free with ads.

Receive-Only Services (Quackr, Temp Number, etc.)

These aren't phone number apps — they're verification code catchers. You get a temporary number that can receive SMS messages, usually from a shared public pool. Anyone viewing that number can see incoming messages.

They work for one specific thing: receiving a verification code from a low-stakes platform signup. They don't work for calls, outbound texts, or any situation where you need a private number that only you can access.

Best for: One-time verification codes from platforms you don't care about.

Pricing: Usually free. You get what you pay for.

Temporary vs. Disposable vs. Second Number

These terms overlap, but they're not the same thing.

Temporary means the number has a finite lifespan by design. You use it for a period and then it ends — either by expiration or by your choice. Burner's prepaid numbers and Hushed's pay-as-you-go options fit here.

Disposable usually means single-use, particularly for verification. Receive-only services like Quackr and Temp Number are disposable — you use the number once and never think about it again. These aren't real phone numbers in any functional sense.

Second number is broader — any additional number on your phone, temporary or permanent. Google Voice, Sideline, and Burner subscriptions all qualify.

Burner spans all three categories. You can use a prepaid number as a temporary disposable, or run a subscription as a semi-permanent second number you delete when the situation changes. That flexibility is the point.

How to Choose the Right Option

Here's the decision in plain terms:

Need a number for one verification code and nothing else? Use a free receive-only service. Quackr or Temp Number will do. Don't use your real number, but don't pay for an app either.

Need a real, functional number for a transaction, a dating cycle, or a few weeks of use? Burner's prepaid option or Hushed's pay-as-you-go. You get a working number that handles calls and texts, and it goes away when you're done.

Need a temporary number that you might keep for a while?Burner subscription. Unlimited calls and texts, monthly renewal, delete whenever. This is for people whose "temporary" might last three months or three years — the point is that you can end it cleanly whenever you decide.

Just want free and don't care about privacy or deletion? Google Voice or TextNow.

The best temporary phone number app is the one that matches your definition of "temporary." If that means a real number you can use and erase on your own terms, Burner's the clearest option. If it means free and you'll figure out the rest later, Google Voice exists.
