If a floral arrangement arrived with an incomplete or missing gift card message, finding out who sent the gift requires contacting 1-800-Flowers customer support directly via phone or live online chat. Providing the customer service representative with the delivery address, recipient name, and any tracking codes or barcode numbers printed on the box allows support agents to look up internal order manifests. While privacy policies restrict unauthorized sharing of customer data, agents will often reach out to the purchaser on your behalf to request permission to disclose their identity.
