In Australia they use "number pairing" in callsigns, so XXX1330 is "XXX Thirteen Thirty" and YYY3013 is "YYY Thirty Thirteen". I've seen a jet on t/o roll slam on the brakes and stop because of that exact reversal of c/s numbers. The other a/c had been instructed to hold position & the jet thought it was for them, despite having been warned of the similar callsign.
