How To Get Chromosome Position Given Rs Number?

I have a list of a 5 hundred thousand SNPs given by rs number. I want to get the chromosome and position for each SNP. For example: input: rs4477212 output: chr1 82154

How can I do it and how long will receive this information?

Probably a biomart solution for this, through R.

You can batch query on dbSNP

If there is a large list of rs ids, download dbSNP VCF file and grep for positions with rs ids
