Correct address for BRP returns?

[Cowley]

In my citizenship ceremony invitation email, the following address is given for BRP returns:

Biometric Product Returns, IFB, 5th floor Lunar House, 40 Wellesley Road, Croydon, CR9 2BY

But in the online guidance (https://www.gov.uk/apply-citizenship-in ... ertificate) a different address is given:

Naturalisation BRP Returns
PO Box 195
Bristol
BS20 1BT

Does anyone know whether it matters? Would it be best for me to follow the instructions in the email?
