How does a US Reverse Geocoding subscription work?

A US Reverse Geocoding subscription runs for the number of lookups or the period of time specified. For example, a monthly subscription of 5,000 lookups is suitable for either 5,000 lookups or one month, whichever comes first.

What happens when a subscription runs out?

It renews at the same level as your current plan unless you have specified another plan or have turned the renewal off. Need to change plans? Change it on the subscriptions page.

How about a one-time subscription?

Easy! After your purchase, select "Off" from the Auto-Renew Plan's dropdown list on the subscriptions page.
