Re: how long new number work for quick security check for UK paypal?
When you add a new number to PayPal it will update after 72 hours
By that I mean if you have number
07888555855 showing when getting a security check but you want to update it to 07888557777 you go into the setting, update the number, make it primary and then after 72 hours the new number will be used for security checks.
