A second phone number for online dating

Swap numbers, not your privacy.

A number you can retire if a date doesn't work out. Your real line never enters the picture, and never gets reverse-searched on Instagram. Real calls, texts and photos with your match, on the phone you already have.

Why daters use a side line

Your number says more than you think.

A phone number can be all someone needs to find your social profiles, your workplace or your address. A side number keeps your number private on dating apps, and gives your match a way to reach you without handing over the rest.

Move off the app without giving up your number

Leaving the dating app for texts is where most people hand out their real number. Give the side line instead and keep chatting with photos, voice notes and group threads.

Harder to trace back to you

Your side number isn't the one attached to your Instagram, your payment apps or your group chats, so there's much less for a curious match to look up.

Keep your voice to yourself, too

Nervous about the first call? Turn on Voice Changer before you pick up and choose how you sound. One tap during a live call.

An easy exit

If it doesn't work out, mute the line or retire the number. No awkward "please delete my number" conversation needed.

How it works

Match, text, meet on your terms.

Set up a dating number before your next match asks for yours, and keep your personal line for the people who already have it.

Step 01

Pick a number

Choose any available number and area code. No SIM, no signup verification. About a minute from open to first text.

Step 02

Give it to your match

When the conversation moves off the app, share the side number. Calls, texts and photos land in SideNumber.

Step 03

Keep it or retire it

Hit it off? Keep chatting. If not, mute the line, or retire the number and start fresh.

Reviews

From someone who learned the hard way.

"I went on three dates from one app last month. One found my Instagram from my phone number within an hour. The next two went through SideNumber."

FAQ

Dating with a side number, answered.

Will my match know I'm using a second number?

It's a real ten-digit US or Canadian number. Your match calls and texts it from their own phone like any other number, with no app required on their side.

How do I keep my number private on dating apps?

Don't give your personal number to someone you've just matched with. Give them a second phone number instead: when the chat moves off the app, share your side number, and your real one stays with the people who already have it.

Can I send photos and voice notes?

Yes. Messaging is unlimited and covers texts, photos, voice notes and group threads, everything you'd send from any modern messaging app.

Can I use a different number for each dating app?

Yes. You can run several numbers in one app. The 3-number plan is $24.99/mo, which keeps each app's matches on their own line.

What if a match gets pushy?

Mute the line, or retire the number entirely. They only ever had your side line, so your real number stays out of reach.

Does a second number make online dating safe?

It keeps your real number private, which removes one of the easiest ways to look you up. It isn't a replacement for the basics: meet somewhere public, and let a friend know where you'll be.
