International Morse Code sequence representing the number 0.

Flag semaphore indicating the number 1. This shape is the Number 1 (Flag Semaphore) and the Letter A (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the number 2. This shape is the Number 2 (Flag Semaphore) and the Letter B (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 3. This shape represents both the Number 3 (Flag Semaphore) and the Letter C (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 4. This shape represents both the Number 4 (Flag Semaphore) and the Letter D (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 5. This shape represents both the Number 5 (Flag Semaphore) and the Letter E (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 6. This shape represents both the Number 6 (Flag Semaphore) and the Letter F (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 7. This shape represents both the Number 7 (Flag Semaphore) and the Letter G (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 8. This shape represents both the Number 8 (Flag Semaphore) and the Letter H (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.

Flag semaphore indicating the Number 9. This shape represents both the Number 9 (Flag Semaphore) and the Letter I (Flag Semaphore). Before delivering any numbers, the sender uses the 'Numbers to follow (Flag Semaphore)' signal. The sender uses the Letter J (Flag Semaphore) to switch back to letters.
