In CW operation, individual digits may be abbreviated by substituting as follows: 1 = A, 2 = U, 3 = V, 4 = 4, 5 = E, 6 = 6, 7 = B, 8 = D, 9 = N, 0 = T (for instance, RST 599 could be sent as 5NN - a shorter message in CW). These are referred to as "cut numbers" and are obtained by replacing all of the dashes in a CW digit with a single dash. Cut numbers are not suitable for transmitting data which already contains mixed alphanumerics, such as [[callsign]]s.<sup>[http://www.qsl.net/zs1an/contesting_faq.html#cut-numbers]</sup>

Two non-standard codes, rarely-used, were coined within the amateur radiotelegraph service. The Young Ladies Radio League (YLRL) organized in 1939 and quickly coined '33' as "Love sealed with mutual respect and friendship between one [[YL]] and another YL".<sup>[http://www.repeater.org/links/links2/73.htm#33]</sup> More recently, '72' has been used in [[QRP]] operation to signify a '73' sent with reduced transmitter power.
