Vanessa fron the Google Maps / Places team has documented the typical turnaround time for the various types of Google Maps updates. As Nyagoslav Zhekov pointed out below, it is important for me to stress that these are the typical turn around times for now - it may change in the future, probably will as Google upgrades their systems right now.
The same questions come up over and over again in the forums, so Vanessa decided to post the ETA for the most common updates.
Here they are:
Updates In Days:
- Newly verified listings (even though it reads “Active” in your dashboard)
- Business titles
- Addresses
- Phone numbers
- Website URLs
- Pin marker moves
- Descriptions
- Hours
- Categories
Updates In A Week:
- Photos
- Videos
Updates In Several Weeks:
- Merged listings
- Duplicate listings
For more details and if you have questions, please check out the forums.

Thanks for the update Barry, been making some changes to a client's Google Places recently and the changes seemed to take forever... at least now I have a typical timeframe to judge against!

These timely stats will help me manage expectations with a new client who needs help to "re-verify" this GP listing that he let lapse. Didn't see this in the roll-call? Will have to pop over to the Forum to find out what the process/routine is to reclaim an aged GP listing.

On Google places I have listed two businesses which have the same address and telephone number on Google places. Google listed one in van hire local search the other in car hire local search. This week the car hire website has shown foe van hire search. Why has this happened
