Oops. That was a 5:00 in the morning typo. I know the number.
I figured that was probably the case. Although the song’s meter still works with a five there. The resulting repetition of the digit five is somehow less satisfying though.
Mine
My husband’s
My mom’s (which has been hers since 1979)
I know my daughter’s and SIL’s numbers are identical except for the last digit, but all I recall is the area code.
Oh, and I remember my childhood number.
Mine, my wife’s and 911.
I remember a couple of long-dead land-line numbers from years ago and nothing at all from today, even my own.
I’m down to five: my cell, my work (landline), my wife, and my mother (the last is also a landline). And a random uncle’s landline.
(This doesn’t include about six additional, possibly defunct landline ones I remember from childhood.)
Our land line
my cell
my wife’s cell
my parents’/my old number
my inlaws’ land line
the number for time and temperature when I was a kid
the mom of my best friend from high school
911
You never know when you might need to call Empire Carpet.
I’m getting pretty good at remembering my wife’s number. That’s only because Walgreens asks for it if I’m picking up a prescription. Still need to look sometimes.
911
My childhood phone number.
The main number at work.
One childhood friends number from 50 years ago.
And of course this one:
- My landline and mobile.
Mine, my husband’s, and each of my parents’. I should memorize my brother’s and his wife’s.
I still remember a childhood house phone number, a former childhood friend’s number, and a former cell number of mine.
I think that the only current number I remember is my own.
But I also remember the old numbers of three of my good friends, and my mom’s old landline, and my uncle’s old landline, and my dad’s old landline, and another friend who I wasn’t as close to except that his number was only one digit off my uncle’s so it was easy to remember…
Plus, of course, the Hotel Pennsylvania, and (like all Clevelanders of a certain age) an old aluminum siding company.
My landline and cellphone numbers. A local friend who I talk to once a week or so.
And, for some reason, the phone number of the house where I grew up in Chicago. I know my sister changed the number after she ended up with the house, so I have no idea why the number sticks in my mind.
Nearly everyone remembers arbitrary things they learned as a kid. Your mind was much less cluttered then and knowing your own phone number and how to use it was a major rite of passage for an e.g. 6yo.
That was (probably) also a big part of the process of you learning how to learn & retain string of arbitrary digits.
e.g., and slightly off-topic, but I recall the license plates of the first two cars my parents had once I was old enough to remember anything. I also remember the two personalized plates I’ve had; one now and one ~15 through 20 years ago. The other 20+ random plates in the middle, mine or my wifes’? I have zero clue. Including my most immediately recent non-personal one from a mere 2 years ago.
Bottom line: kids remember some shit for life. So be careful what you teach the little blighters. 
I know:
my cell
work
My Mom’s cell, which used to be our house land line
the pizza place that was nearest to my old shop
I’ve got those stuck in my head also. I feel safe sharing them at this point, it was 50 years ago. 360 AFC and 470 AFK. That they were so similar struck me even then.
I remember a lot of numbers from years gone by, but very few current numbers.
Aside from the obvious ones (my and my wife’s mobile numbers and our “landline” number), the only number I have memorized is the one for our auto mechanic. And the only reason I remember that one is that their number has the same last four digits as our home number.
I do remember my older brother’s home number because in the last four digits, the first two multiplied equal the last two digits. (Think 5-5-25.) I still have trouble remembering the exchange, though.
Having lived in the Chicago area for close to forty years, dating back to when Empire Carpet was just a local company here…yes, that’s one of them. 
I still remember my childhood landline number - my parents only gave it up in the last 5 years. I also remember two other numbers from my childhood - one was my best friend’s number and the other one was the number of a family I babysat for quite often.
Current phone numbers I remember include my own mobile number, my husband’s phone number, 911 (U.S. emergency), 144 (Swiss ambulance), 112 (Europe-wide emergency) and the number for IT support at work. Because if I can’t log into my computer, I have to call them with my own phone.
I also remember the license plate of the first car I drove. My parents gave me their credit card to buy gas, and the gas station attendant always wanted the license plate number for the receipt.
Oh, 1-877-KARS 4 KIDS
sorry
I did that for some numbers, and would have to press imaginary buttons to tell someone the number.
