How many phonenumbers you know by heart?

None, not even my own phone number. Everytime my phone number is needed, i have to check on my phone for it lol.

We now have 5 sim cards for our phone, one for each country we regularly visit. We don't know a single one by heart except the US number (which we never use).
However we probably spend less than 2 hours a year on the phone, so maybe that's why we don't need to remember the numbers.

My mom, my dad, my sis, and my own pn, but as that mystery7 guy said, I also know some emergency numbers.

911

Parents,Brother,cousin,2 of my hommies,office line,an ex,a fwb and a girl i'm not sure realy where we stand.

I know family and close friends.

I remember quite a few from before the days when we had to use the area code. Old house number, old boyfriends and friends numbers, grandparents, etc. Now I know maybe a dozen or so.

I remember BR-549

Not many. But I do know a shit load of fax numbers by memory.

I had to spend a few mins thinking. 17 is as far as I got which includes my own. Only half of them are still relevant/active numbers though

Not nearly as many as I did pre cell phone era. I do still have my childhood number memorized but it hasnt worked since the 90's. I know mine and my husband's and the dozen or so different numbers for work. Most of those are sequential so it's pretty easy to memorize. And the take out food place across the street from my office.

Numbers I know: mine, brother, other brother, mum, father, step brother, step mother, old work, new work, ex girlfriend, best friend from elementary school, and 911.

That is 13.

I know my dad's old cell number, my mother's old cell number, and the home phone number we used to have in the house we lived in when I was 5. I'm trying to remember the numbers to their new phones with no luck. lol
