821—2.12 (48A) Date of registration. For the purposes of record keeping and determining timeliness of an application to register to vote, the date of registration of an application received from a source other than the United States Postal Service is the date the application is received by the commissioner, or submitted to a voter registration agency, or submitted to the office of driver services, department of transportation, whichever is earlier. The date of registration of an application delivered to the commissioner by the United States Postal Service is the postage cancellation date on the application or on the envelope containing the application. If the postage cancellation date is missing or illegible, the registration date is the date of the second day preceding the application’s receipt in the commissioner’s office.
