How to Reply When He Says Someone Gave Him Your Number
Smart ways to respond when a guy texts saying he got your number from someone else. Set the right tone and keep things moving forward.
When someone reaches out saying a mutual friend gave them your number, you're dealing with a specific dynamic. He's already been vetted by someone you know, which changes how the first message lands. Your reply sets whether this feels like a real introduction or an awkward favor to that friend.
A good reply acknowledges the mutual connection without making it weird, and it gives him something to work with. You're not rejecting the premise, that's unfriendly. But you're also not just saying "oh cool." The goal is to signal you're open to talking while staying in control of how much energy you give back.

Someone vouched for him, so read it as a soft introduction
When a guy leads with "[friend] gave me your number," he's doing the social work for you. He's not a cold stranger. Someone in your circle thought you two might click or at least get along. That context matters.
What he's signalling is that he got permission from a mutual person, not that he stalked you down. He's also testing whether you'll even engage. If you shut it down hard, that gets back to your friend. That's why your tone needs to be warm enough that you're not making anyone uncomfortable, but measured enough that you're not faking interest.
Your reply has two jobs here
First, confirm you're okay with the mutual friend sharing your number. You don't have to make a big deal of it, but a quick acknowledgement that you know who gave it out removes the creepy feeling. This takes one sentence.
Second, give him an actual opening to continue the conversation. Don't just say "oh cool" and make him guess whether you want to talk. Either ask something about him, comment on what he said, or make a light suggestion about what comes next. He's already taken the step of texting. Match that halfway.
Same day replies keep this from going stale
Respond while the day is still happening if you can. This is day one of contact. If you wait three days, it reads like you forgot about him or had to think hard about whether to reply. Both kill momentum.
If he doesn't reply to your message after you've sent something solid, wait 48 hours minimum before sending anything else. If a week passes with nothing, he's not coming back. Don't follow up twice. The mutual friend isn't worth awkwardness if he's gone silent.
Why these replies fail
“Wait, who? I didn't give anyone permission to share my number lol”
This makes it confrontational right away and puts the burden on him to defend himself when he was just following your friend's lead.
“Oh hey! That's funny, [friend] actually mentioned you might text me haha. How's it going?”
Saying he told you he might text makes it look like you two were set up deliberately, which shifts the pressure and removes his agency in reaching out.
“Thanks for reaching out. I'm always open to meeting new people.”
This is so formal and non-committal it signals you're going through the motions as a favor to your friend, not because you have any actual interest.
Common mistakes
- Asking him immediately who gave him your number, as if you need to verify him first
- Over-explaining why your number is out there or apologizing for it
- Responding so enthusiastically it looks like you've been waiting for a guy to text you
- Ignoring the mutual friend entirely and replying like he's a stranger
- Taking days to reply, which signals you're not interested but don't want to say it
Questions people ask
- Should I ask him who gave him my number to verify he's telling the truth?
- Only if you really don't know who it might be. If you have a few friends it could've been, hold off. Let the conversation flow first. If something feels off, you can circle back. Starting with verification feels like an interrogation.
- Is it bad if I take a few hours to reply?
- No. A few hours is fine, especially if it's evening or night when he texted. Same day is the goal. If it's been a full day and you're just now seeing it, don't sweat it. Just don't wait on purpose to seem busy.
- What if I'm not interested but feel bad because he knows my friend?
- A short, kind reply is enough. You don't owe him a reason. Something simple and honest keeps it from being weird with your friend. Ghosting him completely will probably make it back to them anyway.
- Should I bring up the mutual friend again after the first message?
- Only if it comes up naturally. Your second or third message should shift toward getting to know him as himself, not as the guy your friend sent your way. Don't keep looping back to the friend.
