There are essentially 3 reasons the girl won't give her number out if you have been running even semi decent text game. The first is that she is paranoid about stalkers and whatnot. This is the only category that is still worth pursuing . Here is how I handle it : https://www.playingfire.com/sexy-redhead-wont-give-number-tinder-lay-report/

The second reason that she is a time waster . And the third is that she is a prude who thinks a number is a "big deal". So how do you tell between the first category and the the second/third? Look for two things: investment and the willingness to talk about sex. You can see in my example both of those criteria were meat thus I assumed it was due to the stocking paranoia . After we meet and banged I brought up the number thing and she confirmed that she had a bad experience with the guy in her past stoking her .

Tinder guys spamming a girl's phone is a legitimate problem.

Personally when a girl doesn't want to give me her number on tinder, 90% of the time she tries to curve me to snapchat.
My response is "Ouch snapzoned"
At this point it's about 50-50. She either says "lol alright it' s xxx-xxx-xxxx" or "yeah bla bla bla"/no response.

The other 10% I'll just say "It's cool what's your sc"

If she won't give me the digits but our plans are at least a day in advance, I'll add her on snapchat, send a few snaps back and forth making specific plans, then leave her unopened for a few hours. At that point I'll say "Don't mean to ghost you I'm not on here alot". She says it's cool/whatever and I say text me xxx-xxx-xxxx.
If it's for later that day, I think it's better to just stick with snapchat.

Every time I've seen a girl from tinder on snapchat it's ridiculous. 10 or more unopened snaps from hours ago, all from guys. She opens them and it's shitty selfies with captions like "Wyd", "You dtf", "Where you at". I think this is why snapchat leads are so flakey.

I usually do soft close -> hard close -> number. In my opinion it feels more natural going for the hard close immediately after the soft close instead of asking for her number in between. If they won't send you their number after a successful hard close, which is rare, I usually don't make a big deal out of it. The date is your primary objective, not her number. You can also try something like "Don't worry, I won't spam your phone", but I'm not sure on this. Maybe Alex can chime in.
It's also easier if she has a reason to send you her number. I had a girl that asked me where she could park her car and I told her to send me her number so I can send her Google Maps coordinates

Do i understand corectly that after having a wine or coffee they wont give you the number?
