Hi Rob, There appears to be no mention of any 540 days expiration for the MOBILE_ADVERTISING_ID value of the CustomerMatchUploadKeyType <https://developers.google.com/adwords/api/docs/reference/v201710/AdwordsUserListService.CrmBasedUserList#uploadkeytype> field of the CrmBasedUserList. MembershipLifeSpan <https://developers.google.com/adwords/api/docs/reference/v201710/AdwordsUserListService.CrmBasedUserList#membershiplifespan> of "10000"/"no expiration" should be applicable as long as it is a CrmBasedUserList.
Also, the documentation that you sent regarding the Mobile ID does not appear to refer to uploads via the AdWords API as CrmBasedUserList objects focus more on uploading emails <https://developers.google.com/adwords/api/docs/guides/remarketing#customer_match_with_email_address> and phone numbers <https://developers.google.com/adwords/api/docs/guides/remarketing#customer_match_with_phone_number>. I would recommend that you reach out to the AdWords Community Forum for more information regarding this matter.
