Excellent App! Until you need to change your residence address or phone number, then a nightmare! UPS and MyChoice UPS are separate accounts. You cannot change your residence address or phone number in profile on MyChoice UPS. Changing UPS does not change MyChoice UPS. One-sided, not yours. You must contact UPS by email or phone to change your residence address and phone number. Response time is excellent. Closed MyChoice UPS and use only the UPS tracker. Always excellent reliable service👌
