免税
免税指国家为了实现一定的政治经济政策，给某些纳税人或征税对象的一种鼓励或特殊照顾。减税是从应征税款中减征部分税款；免税是免征全部税款。我国幅员广阔，经济情况千差万别。可能因为国家经济政策的要求，需要对某些行业、企业或产品的发展给予一定的支持和鼓励。
可能因为某些纳税人遭受自然灾害发生意外损失，需要给予特殊照顾；也可能因为生产经营条件发生较大变化，而税法规定的税率一时又不宜于调整，需要给予特殊照顾，等等，这就需要采取减税免税措施把税法的统一性和必需的灵活性结合起来，因地制宜地对待征税中的各种特殊情况。

对的。美国的邮编就是由5 个基本的号码加上4 个号码。
A ZIP Code is the postal code used by the United States Postal Service, which always writes it with capital letters. ZIP is an acronym for the Zone Improvement Plan。
ZIP+4
In 1983, the US Postal Service began using an expanded ZIP Code system called "ZIP+4", which are often called "plus-four codes" or "add-on codes." A ZIP+4 code uses the basic 5-digit ZIP plus an additional 4-digits to identify a geographic segment within the 5-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. Use of the plus-four code is not required except for certain presorted mailings. In general, mail is read by a Multiline Optical Character Reader (MLOCR) that instantly determines the correct ZIP+4 code from the address and—along with the even more specific Delivery point—sprays an 11-digit POSTNET barcode on face of the mailpiece. This technology has greatly increased the speed and accuratecy of mail delivery and in turn, kept costs nearly constant for over a decade.
The first digit of the ZIP code is allocated as follows:
0 = Connecticut (CT), Massachusetts (MA), Maine (ME), New Hampshire (NH), New Jersey (NJ), Puerto Rico (PR), Rhode Island (RI), Vermont (VT), Virgin Islands (VI), APO Europe (AE), FPO Europe (AE).
1 = Delaware (DE), New York (NY), Pennsylvania (PA)
2 = District of Columbia (DC), Maryland (MD), North Carolina (NC), South Carolina (SC), Virginia (VA), West Virginia (WV)
3 = Alabama (AL), Florida (FL), Georgia (GA), Mississippi (MS), Tennessee (TN), APO Americas (AA), FPO Americas (AA).
4 = Indiana (IN), Kentucky (KY), Michigan (MI), Ohio (OH)
5 = Iowa (IA), Minnesota (MN), Montana (MT), North Dakota (ND), South Dakota (SD), Wisconsin (WI)
6 = Illinois (IL), Kansas (KS), Missouri (MO), Nebraska (NE)
7 = Arkansas (AR), Louisiana (LA), Oklahoma (OK), Texas (TX)
8 = Arizona (AZ), Colorado (CO), Idaho (ID), New Mexico (NM), Nevada (NV), Utah (UT), Wyoming (WY)
9 = Alaska (AK), American Samoa (AS), California (CA), Guam (GU), Hawaii (HI), Northern Mariana Islands (MP), Oregon (OR), Washington (WA), APO Pacific (AP), FPO Pacific (AP).
全美共有五个州免消费税，分别是Oregon（俄勒冈州），Alaska（阿拉斯加州），Delaware（特拉华州），Montana（蒙大拿州）和NewHampshire（新罕布什尔州）。
目前很多转运公司都会提供2个美国收货地址，一个是是免税州的，一个是普通的，很多人刚刚接触转运，完全不知道选择那个地址，上面说到了发往免税州可以不用支付消费税，所以咱们可以把东西发到免税州地址，这样就不会被征收消费税。另提醒不是所有商品发往免税州都划算，有的转运公司使用免税州地址会比CA运费贵，加州的发货速度会比免税州快一些，如果转运公司可以直接从免税州直发，或不会多付运费，还是发免税州划算些。
