Verizon does port numbers on weekends. The timeline for the porting process depends on the type of number being transferred. For mobile numbers, it usually takes 4-24 business hours to complete the transfer. On the other hand, landline numbers can take 2-10 business days to transfer. Once the porting is complete, Verizon will send you a free text notification. In case your new phone doesn't work after the transfer time, you can call their Port Center at 888.844.7095 from another phone for assistance. Verizon allows you to bring your number from another carrier using various methods, including dialing #PORT from the phone you want to transfer or generating a Number Transfer PIN through My Verizon.
