Short code 86753: Venmo
Venmo's verification and sign-in codes come from one five-digit number. Knowing that number is the simplest defense against texts that only pretend to be Venmo.

The five-digit number 86753 belongs to Venmo, the payment app that PayPal has owned since it bought Venmo’s parent company, Braintree, in 2013. Venmo’s own help center names 86753 as the number its texts come from, and that is the source to trust over any list compiled by someone else.
What Venmo sends from 86753
Most of the traffic is security codes. When someone signs up, Venmo texts a code to the phone number on the account so the app can confirm the number is real, and some features, sending payments among them, stay locked until that step is done. Signing in from a phone or computer Venmo does not recognize also triggers a code by text. People who switch on text notifications in their settings get account notices from the same number, such as word that a payment has arrived.
Venmo tells users never to share those codes with anyone and says nobody at Venmo will contact them to ask for one. A code that arrives when nobody on the account was signing in means someone else may be trying to, and changing the Venmo password is the sensible response.
Stopping and restarting the texts
Replying STOP to 86753 ends the texts, as the carrier rules for every short code require, and a HELP reply should bring back Venmo’s contact details. The catch is that STOP can also cut off the security codes, which leaves sign-in from a new device harder. Venmo’s help center tells people who stopped receiving codes to text START to 86753, which turns the messages back on. If START makes no difference, the short code may be blocked at the carrier: Venmo’s advice is to ask the phone company to make sure short code messaging is enabled on the line.
Texts that only look like Venmo
Impostor messages rarely come from 86753 itself. They arrive from ordinary 10-digit numbers or email-to-text addresses and usually carry a link: a payment waiting to be claimed, an account about to be frozen, a login to confirm. The codes Venmo sends are digits to type into the app, and a real payment shows up in the app itself. When a Venmo-branded text comes from any number other than 86753, or asks for a code, a password or bank details, the safe response is to ignore it, open the app directly, and forward the message to 7726 so the carrier can log it as spam.
