Sending 2 passports back for renewal

[Rollergirl11]

Should I send them in the same envelope or separately?

Depends if they are going to the same passport office as often they are directed to different ones. One year I did 3 renewals and they went to 3 different addresses

Always done individual

Separately - the address is unique for each passport because it includes the reference number of the renewal.

If they were both going to the same address then you'd need to put both reference numbers on the envelope. Probably easier to track if you do them separately

Ahh yes I hadn’t spotted that it had the reference no included in the address.

I put two in the same envelope with no problem. Just put both reference numbers on the front

Individual because the address you send to has your individual tracking reference included in it.
