电报公司根据要发的信的长度收费。商业代码精心设计了五个字符组成一组的代码,做为一个单词发送。比如:BYOXO(Are you trying to crawl out of it?);LIOUY(Why do you not answer my question?);AYYLU(Not clearly coded, repeat more clearly.)。这些五个字符的简语可以用摩尔斯电码单独发送。在网络用辞中,我们也会说一些最常用的摩尔斯商用代码。现在仍然在业余无线电中使用的有Q简语和Z简语:他们最初是为报务员之间交流通信质量、频率变更、电报编号等信息服务的;还有在手提电话的讯息铃声中,厂商依然会将“SMS(...--...)”一句的摩斯密码加入,而在香港的无线电视里,自开台1967年起,每次新闻报道亦会在背景音乐中播放“NEWS TODAY”的音频。
现代国际摩尔斯电码是由 Friedrich Clemens Gerke 在1848年发明的,用在德国的汉堡(Hamburg)和库克斯港(Cuxhaven)之间的电报通信。1865年之后在少量修改之后由国际电报(International Telegraphy)大会在巴黎标准化,后来由国际电信联盟(ITU)统一定名为国际摩尔斯电码。
