# Quick way to check what 'tape' a stock belongs to?

For the SIP feeds, there is the CTA and the UTP plan and they cover Tapes A,B and Tape C respectively. Is there an easy way to check on google what tape a stock would belong to? Particularly when it comes to disambiguating A and B?

You can pull a list of all stocks easily. See this question. You can get nasdaqlisted.txt and otherlisted.txt from here. nasdaqlisted.txt is clearly Tape C. otherlisted.txt contains an Exchange column which can be used to determine Tape A or B. If it is N it's listed at NYSE and therefore Tape A, otherwise it's Tape B.

Also, NYSE publishes a symbol list these days as well. FTP to ftp.nyxdata.com and look at the NYSESymbolMapping and ARCASymbolMapping directories.

Thanks this is helpful. –  Palace Chan Feb 20 at 0:20

As far as I know, Tape A, if it's a NYSE proper stock, Tape C, if listed on NASDAQ, else Tape B (e.g. including those, which finance.google.com shows as NYSEARCA)
