Hello Gabriel,

Use a combination of a Custom track with the Table browser for this type 
of query

The basic steps would be to:

1) Create a BED file of your coordinates and upload as a custom track. 
If strand is important (probably is) then use at least a BED6 file 
(name/score can be made-up values)
http://genome.ucsc.edu/goldenPath/help/customTrack.html
http://genome.ucsc.edu/cgi-bin/hgCustom

2) Go to Table Browser http://genome.ucsc.edu/cgi-bin/hgTables (see help 
links in top paragraph). Check to verify that your data appears in the 
group menu "Custom Tracks".

3) Now, set the group, track, table for the dbSNP track (or whichever 
SNP track you are interested in - if more than one, do them as separate 
queries). Click on "describe table schema" to understand contents (top 
of page), linked tables (middle of page), and details/methods (bottom of 
page). Go back to query page.

4) Create a filter by clicking the intersection "create" button. Select 
your custom track as the filter.

5) Leave output as default (all field from selected table), name output 
file for download, and submit.

6) The default output has the SNP rs numbers, genomic locations, and 
other attributes. An alternative is to change output format to: 
"selected fields from primary and related tables" where you can limit 
the columns of output from the main file and/or add data from linked tables.

Coordinates for the SNP table follow our standard 0-based start format. 
Your coordinates must also be in this format for the intersection to 
work. http://genomewiki.ucsc.edu/index.php/Coordinate_Transforms

Also, not all source input SNPs may map according to the track's 
methods/rules - the track details page lists possible reasons for 
alternate mapping/non-mapping and exception notations.

Good luck and be sure to check out the great examples in both the Custom 
track and Table browser help if you get stuck. Please write back if 
anything is unclear,
