Return of ILR BRP card, the correct address-Urgent PLZ

[ToneGen]

Hi All,
I have had my ceremony and now I need to send the BRP card cut in half along with my wife's back to Home office.
The address on the Approval letter is different to that of HO website https://www.gov.uk/becoming-a-british-c ... p-ceremony

The one in Approval letter is,
POL Returns,
P.O.Box 195,
Bristol BS20 1BT

Online says,
Freepost RRYX-GLYU-GXHZ
Returns Unit
PO Box 163
Bristol
BS20 1AB

Which one should I send it to? or either are fine? I think 1st one is paid post?
My second query is can I put both out cut cards in a single envelope?

Appreciate your help..

Either address, it is the same place. One is where you pay for postage the other is a freepost address.

Yes to both in one envelope.
