Photograph is recommended but not required when applying for the CNR/SDA program. Callers who sent in a photo but received a swipe card without a photo, can continue using the swipe card with no penalty or break in service. Participants may need to present an alternate form of ID along with the swipe card upon entering the taxicab. For additional questions related to photos, please contact CNR Program Office at 301.948.5409 (Monday - Friday, 8:00 AM - 4:30 PM).
