When I got my ISC2 and ISACA certs, I saw they took 4 weeks to process. I think in one case it was 3 weeks.
With ISACA, when you pass their tests you have 5 YEARS to submit paperwork to get the certification. ISACA has made it clear that you are fine to share out on social media that you've passed, but that is NOT to go on your resume or LinkedIn profile as it could give the wrong impression you have the cert. Would like ISC2 would be the same.
Not sure on other certifying bodies, but others expect the application BEFORE you take the exam (PMI, DRI, and maybe EC-Council does this).

It was around 4 weeks up until a few months ago. I won't go into the reasons why it increased, but it went up to over 9 weeks. Thankfully, it is now steadily making its way back down. I recently had an endorsement completed in just over 7 weeks. Hopefully they will get back to 4 weeks again in the not too distant future!
