Question about reviews mentionning a 4-digit number

[janchris3870]

I have tried to find the explanation in the forum but could not.
Many reviews have a title like [Name] + [4digit number] eg. Sally 4556, sometimes with a mention of ERS.
I found ERS is a website with somes ads, but I did not find any 4 reference digit number.
So what it the meaning of this number?

last four digits of their telephone number. There are many Service Providers with the same name

the practice of using the last four digits of the phone number stems from the previous board policy of not allowing the full phone number except in the case of paid up perb advertisers. the last four digits served two purposes, that of identifying different women using the same name; as well as providing a convenient character string to use in the case of searches for information or reviews on the escort in question

thankfully we have more enlightened rules now that currently allow the full contact phone number to be given as well as a link to a website for non-advertisers. however, many members are late adapters, and still cling to the old habit of only giving the last four digits

giving a brief contraction of the site where an escort advertises is a courtesy that most reviewers provide so other perb members can go to look at pictures, read the wording of the ad, or find other details not given in the review

ERS = erslist
CL = craigslist
BP = backpage
TER = the erotic review
EC = escorts canada
etc
