Smallest netblock that providers will accept?

Hello All,

I am curious as to the routing polices of the bigger providers such as
ATT, L3, Internap, Qwest, Etc Etc...  Is there a standard size
netblock that these providers will accept? For instance, if customer
"A" gets a /22 from ARIN and his upstream provider is ATT and L3, what
would the smallest block be that those providers would accept from
customer "A"? Would they accept something as small as a /24?

Thanks,
Mike
