According to one embodiment, an RFID tag issuing apparatus includes a communication instructing unit, a search unit, and a misalignment amount detecting unit. The communication instructing unit instructs a reader-writer unit to communicate with the RFID tag at a reference position that is reached when the label is carried by a predetermined amount in a predetermined direction after the specific position on the label is detected by a label position detecting unit. The search unit repeats a carrying of the label and a communication instruction to the reader-writer unit when communication cannot be established with the RFID tag, and thus searches for a communication-available range with the RFID tag. The misalignment amount detecting unit detects an amount of carrying of the label to reach the communication-available range from the reference position, as a misalignment amount of the RFID tag.
