In more recent computers such capabilities are almost always implemented in software rather than the CPU's instruction set, but BCD numeric data are still extremely common in commercial and financial applications.
In modern [[mobile telephony]], the telephone numbers dialed are sent in BCD format, as well as operator ID, [[International Mobile Equipment Identity|IMEI]], [[International mobile subscriber identity|IMSI]] (SUPI), et.c. They are sent as packed BCD-ecoded variable-length arrays terminated by 0xF.<ref>{{cite web|url=https://www.etsi.org/deliver/etsi_ts/124500_124599/124501/16.10.00_60/ts_124501v161000p.pdf|title=Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3.

There are tricks for implementing packed BCD and zoned decimal add–or–subtract operations using short but difficult to understand sequences of word-parallel logic and binary arithmetic operations.<ref name="Jones_1999_AT" /> For example, the following code (written in [[C (programming language)|C]]) computes an unsigned 8-digit packed BCD addition using 32-bit binary operations:
