dbSNP download and merge to my data

Question

[SeoG]

Hello, after downloading the rsID from dbSNP, I merged it with my BED data, but the rsID was missing. I searched for that snp on ncbi and it was an existing snp. If anyone knows the problem, I'd appreciate it if you could let me know.

download dbSNP at :

https://ftp.ncbi.nih.gov/snp/organisms/human_9606_b151_GRCh37p13/VCF/00-All.vcf.gz

merge in linux:

bedmap --echo --echo-map-id --delim '\t' 
/mnt/HDD1/reference/dbSNP/linear_positions_no_chr.bed /mnt/HDD1/reference/dbSNP/hg19_dbSNP.bed 
> /mnt/HDD1/reference/dbSNP/answer.bed

Please attach at least some line of your input BED file, and use the code formatting or ticks for code and commands.
