加拿大银行系统的确有点混乱。比如，支票上显示的分行号码 branch number，也就是交易号码 transit number，是4位数的，比如4567，即使网上银行账户里也显示的是4位数，但是，在日常生活中填写各种表格的时候，上面提示“填写你的5位transit number”，有的网上系统必须要求你填写5位数。你说混乱不混乱？
其实，只要在4位数后面加一个数字就可以了。这个数字对应了加拿大某一个地区。比如，我的账户是在多伦多开的，那么这个数字就是2，因此5位数的交易号码就是45672。
下面是各个地区对应的数字：
0 are located in British Columbia
1 are located in Western Québec including Montreal and surrounding area
2 are located in Ontario including Toronto and surrounding area
3 are located in Nova Scotia, Prince Edward Island and Newfoundland excluding Labrador
4 are located in New Brunswick
5 are located in Eastern Québec including Labrador
6 are located in Eastern Ontario including Ottawa and surrounding area
7 are located in Manitoba and North-Western Ontario
8 are located in Saskatchewan
9 are located in Alberta
